<ul>

-<li>All implementations will be always be called in an undefined order except that any main implementation (=the implementation without an event attribute) will be called last.</li>

-<li>Event attributes may only be used for event functions which are a procedure or are a function which return a Boolean. In the latter case all implementations much return True for the event function to be treated as returning True and an implementation returning False does not stop the calls to the other implementations.</li>

<li>If the event function uses <tt>var</tt> parameters then the value will be passed on from implementation to implementation.</li>
|
|
|
<li>To call an implementation with an event attribute yourself from [Code] you should use the normal name of the function, just as if the implementation had no event attribute.</li>
